This inventionk relatesl to improvements in tools, and lmore n .especially to improved methods and means for mounting toolhan-l dles.

. In the .mounting ofy handles for tools, and

especiallyrevolving tools, itis of the utmost importance not only that the handle revolves Y freely. vwith respect to the tool shank on which itis mounted, but that the mounting means be such' that the angular, rough lor projecting parts are eliminated. Suchsecuring devices as screws, pins, nuts or lock- 'ing rings are objectionable, not only by reason of theirl cost, but'also onv account of the vfact that theyalmost invariablyv leave rough parts orprojectionson thebhandle.y Even lwhen these securing devices are so arranged that projections are, as farxas possible, avoided, .they are aptvto become loosened and displaced with use of the tool, with consequent annoyance and injury to the hand of the user. Y f v One object of the 'present invention rto' provide securing vmeans for a tool handle which are containedwithin` and are incapable of projecting outside of the handle.

Affurthe'r object ofthe invention is to provide a handle and securing means therefor constructed entirely of sheet metal.

A further object of the invention is to provide a tool handlev and means for securing the handle to a shank, adapted to be formed and secured together by spinning or an equivalent operation. l

With these and other objects in view, my 'invention consists in the novel combinations and arrangements of parts which will be hereinafter described and are illustrated in the drawings in which: n

Fig. 1 is a vertical section thru my im-` proved tool handle, showing said handlel attached to the shank of a tool.

Fig. 2 is af section on the line 2-2 o Fig. 1. p

Fig. 3is an elevation of the handlein a position at right angles to the Fig. 1 vposition, a part of the handle proper being broken away to show the securing device.

The shank 5 to which the handle is to be secured comprises an end lsection 6 of reduced diameter, terminating in a shoulder 7. A.v second shoulder 8 is formed on the shank a short distance below the shoulder 7, and in 'the embodiment of the invention which has been selected for the purpose of Application filed November 6, 1924'. Serial No. 748,034. y

yTOOL HANDLE.

illustration, the shank below the shoulder comprises aitapered section 9.

The handleproper comprises two hemij f f spherical shells 1() and 411, which are perforated to` receive-the shank 5. The perfora-l tion in thelower section or shell 11 is bound ed byan inturned flange12, and is of such diameter vthat the handle will turn freely on the shank `5. Theperforationin the upper half 10 of the handle is surrounded by the inturned flange 13, adapted to iitloosely yover the reduced end 6. 'Thel'langes 13 is of such a-height that when the end thereof restsl on 'the shoulder y the exteriorof' the 'i n .7o l j handle is approximately Hush with the end of the shank. l

The means for securing the twosections of the handle together comprises a` lip or.

yledge 14, extending outward' fromthefr'im l.

of one section of the handle, and a bead 15r on the other section which is spun or other-y wise turnedover the lip 14, as clearly illusi trated in Fig.,1. Y

The means for securing the handle tothe f shank comprises 'a member. 'having extending springflingers 16,17, adapted to engage-the ,shoulder 8. yIntegral with thelingers 16 and 17 is a clip 18 in the shape of a segmentk of a spherical shell, which lies adjacent vthe interior ofthe shell section 11.` The segment is perforated to receive the inturned flange 12, and :fits ltightly about said flange.

The parts of my improved handle may be formed'and secured together by any suitable methods. In a preferred method,`the parts are both Ashaped and secured together by spinning. Blanks for the two sectionsv of the handle are struck from sheet stock, after which the blanks are separately spunto shape. The securingmember is blanked from sheet stock and spun l or' otherwisev formed inplaceyand the securing fingers turned inwardly to such an extent that their .ends will engage the shoulder l8 without ion pressing tightly on the `tapered section 9'- of Y the shank 5 below'the shoulder 8. The two halves of the handle are then secured to? gether by spinning the bead 15 over the lip handle thru the perforation in the lower sec- 14.` The shank 5 is then inserted inthe z tion 11, the spring fingers being spread apart slightly 'by the part of the shank-interme diate shoulders 7 and 8. As the end 6. of thek shank 5 arrives at aY point substantially iiush with the outside of the shell, the fingers 16 QR l 'limited to the precisetorni which has 'heen-l described and is illustrated in thefdravvings,

4hut `itiis tolse construed as coveringallequivalent devices falling` Within thefscope'offthe appended claims.
